The fourth production in Branagh’s Garrick season is the revival of an odd-couple romp he brought to the Lyric, Belfast in 2011. Sean Foley (best known for his superlative Branagh-directed Morecambe and Wise tribute The Play What I Wrote) adapts and directs this nostalgic English version of Francis Veber’s 1969 French farce, which wastes no opportunity for dropped-trousers, door-slamming, mistaken-identity slapstick.
